the only thing that i would have a question on is how you knowed wich colors to use at wich place, and how you knew how much and were... i guess this might be a thing that you would have to teach yourself, but maybe you can give me some helpful input, my coloring sucks XD

is just practice i guess, i learn from friends colorist, inschool i learn basic color teory, donīt worry u are still very young i start coloring more older than u, just hace to practice study from the people u like is art, not jus comics, painting masters, movies are a good way to see how ligth work
